Memory modules are generally very generic. DDR memory is also backward compatible within its own series. A DDR3-1333 can be used in a DDR3-1066 application, for example. SODIMM memory does not need to be used in pairs like the older SIMMS required. Make sure you have the correct model as some models look similar.
